CHANGE LOG:
FIXED an issue that was causing players to not be able to join their server after installing CustomRecipes. It would give them a DecoderException error. This was observed on Purpur 1.21.1, but it may have affected different versions and APIs as well.
The issue was based on the client only supporting enchants up to level 255; however, the generated recipe files attempted enchants at level 300. I have updated the default recipe files to have enchants of 255 to fix this issue.
Refer to
issue #64 for more details.
